Rail Transit: Track Detection RTK Survey Instrument

The rail track detection RTK system is composed of an online NRTK service, a track-mounted RTK survey receiver, a high-precision attitude sensor, a data transmission unit and a track data analysis module. The base station outputs real-time differential data to support high-precision positioning. The equipment collects real-time 3D coordinate data of rail tracks, detects track flatness, displacement and settlement deviation. It provides accurate measurement data for track maintenance, deformation analysis and rail engineering acceptance.
